TROLLING ATTACHMENT FOR OUTBOARD MOTORS Filed June 13, 1932 2Sheets-Sheet 2 In um (01' Patented May 16, 1933 AVERY RICHARDSON, OFTACOIVLA, WASHINGTON TROLLING ATTACHMENT FOR OUTBOARD MOTORS Applicationfiled June 13,

This invention relates to a trolling device and in accordance with thepresent invention such a device is provided for use as an attachment tooutboard motors.

Briefly the invention consists in the provision of means whereby atrolling disk may be readily applied to the propeller shaft of theoutboard motor.

The invention together with its numerous objects and advantages will bebest understood from a study of the following description taken inconnection with the accompanying drawings wherein:

Figure 1 is a side elevational view showing the attachment applied tothe propeller shaft of an outboard motor.

Figure 2 is an elevational view taken at right angles to Figure 1 onlysuch parts of the outboard motor assembly being shown as is necessaryfrom an understanding of the invention.

Figure 3 is a sectional elevational View taken substantially on the line33 of Figure 2, and

Figure 4: is a plan view of a nut forming part of the invention.

lVith reference more in detail to the drawings it will be seen that 5designates generally a conventional outboard motor the same includingamong other parts the propeller shaft 6 and propeller'hub 7.

In accordance with the present invention a retaining nut for thepropeller hub 7 and adapted to be applied to a shaft 6 is pro- 35 vided,and the nut designated by the reference character 8 is provided withinternal screw threads whereby it may be readily threaded on to the pinor extension 6a of the propeller shaft as shown in Figure 3. The nut8 isalso 40 provided with a series of spaced apertures 9 for accommodating alocking pin such as a cotter pin 10 that is adapted to extend throngstwo of such apertures 9alining with a transverse opening provided in theend or threaded extension 6a of the propeller shaft.

1932. Serial No. 616,980.

Formed integrally with the nut 8 is a stem or shank 11 that is of lessdiameter than the nut 8. The stem 11 is adapted to accommodate the hub12a of a trolling disk 12, and

From the description of the invention thus far it will be seen that thetrolling disk 12 may be'readily attached to the propeller shaft of anoutboard motor 5 for position directly rearwardly of the propeller andwill in no wise interfere with the efficient operation of the propeller.

Itis also apparent that the nut 8 may be readily removed by removing pin10 and unscrewing the nut from the end 6a of the shaft. Likewise, it isapparent that by removing the cotter pin 15 the disk l2 m'ay be removedwithout disturbing the position of the nut 8 on the propeller shaft.

'Even though I have herein shown and described the preferred embodimentof the in- 7 vention, it is to be understood that the same issusceptible of further changes, modifications and improvements comingwithin the scope of the appended claims.

Having thus described my invention, what 0 I claim as new is:

1. A trolling attachment for the propeller shaft of an outboard motorcomprising a trolling disk, a stem extending centrally through the disk,means for retaining the 5 disk rotatably mounted on the stem, and meansat one end of the stem for securing it to one end of the propellershaft.

2. In combination with the propeller shaft of an outboard motor, anutadapted to be threaded on one end of said shaft, an axial stem integralwith said nut and a trolling disk rotatably mounted on said stem.

3. In combination with a propeller shaft, a propeller hub retaining nuthaving threaded engagement at one end of said shaft, and a trolling disksupporting stem of a diameter less than the diameter of said nut andextending axially from one end of the nut.

In testimony whereof I affix my signature.
